ANDY MURRAY is praying for two in a row when he faces Novak Djokovic in today’s Miami Masters final.

The pair have already clashed twice this year. Djokovic came out on top in the last four of the Australian Open in January but the Scot got his own back when he sank the Serb in Dubai last month.

Murray has beaten the world No.1 five times in 12 encounters but reckons he now has the game to see off his old rival even though he goes into the final short of match action after Rafael Nadal pulled out injured ahead of their semi.

The world No.4 – who beat Djokovic in the Miami final in 2009 – last night said: “We have played a couple of times here and he easily won the first one in 2007.

“But three years ago I comfortably won 6-2 7-5. Both of us were quite immature at the time though and now we are very experienced on the tour.

“It is always a good test to play against the top man in the world to see where your game is at.”

Murray is chasing his second title of the year after beating Alexandr Dolgopolov in Brisbane in January.

He has dropped just one set – against Janko Tipsarevic in the last eight – en route to the final.

But Murray has had two walkovers, against Canadian Milos Raonic in the third round and against Nadal on Friday night when Murray insists he was itching to take on the Spaniard.

He said: “I have been working with my coach, Ivan Lendl, for a couple of months on certain tactics that would work against Rafa, Novak and Roger Federer.

“It would have been nice to see whether or not those things were working.”

Nadal, 25, has been dogged by knee problems throughout his career. He retired from a last-eight clash with Murray in the 2010 Australian Open and missed more than two months of the 2009 campaign, including a Wimbledon defence.

On all of those occasions the world No.2’s right knee was the problem – now it’s his left and it hampered him during his quarter-final win over Jo-Wilfried Tsonga.

Nadal said: “It looks like the same kind of thing as what happened a few times in the past. Hopefully with the right treatment, I’ll be fit to start practice on clay.”

Djokovic beat Argentina’s Juan Monaco 6-0 7-6 (7-5) to reach the final. The Serb lost only eight points in the first set. But Monaco battled back in the second, forcing Djokovic – who served for the match at 5-4 – into a tie-break before the defending champion won on his second match point.
